Buickx Posted May 1, 2019 Report Share Posted May 1, 2019 My hot springs sovereign has a flashing red power light about 30 seconds after flipping on the heater breaker. I replaced the circ pump, and thermistors, but I'm still not getting much water flow through the circulation pump. What else could be causing the flow issue?

Hot Spring Official Posted May 2, 2019 Report Share Posted May 2, 2019 When was the last time you cleaned or replaced your filter. You may also have other restrictions in your circulation plumbing. Your local Hotspring dealer could help you get your tub running again. Quote Link to comment Share on other sites More sharing options...
Buickx Posted May 2, 2019 Author Report Share Posted May 2, 2019 i replace my filters every 4 months. i had it up and running for about two weeks after a fresh fill, with chemically cleaned filters, before the red light started flashing. i checked for air locks and replaced the circ pump, but the problem remains.
